A really strange thing

[MarineManiac]

hey I'm just curious but what setting do you need to max out in order to see the scenery outside of the zoo.  Because I just set my settings to best proformance, so my graphics are really low now, but I'm picking which ones I want high.  But when I went into my game there is nothing but black on the outer edges, where there should be a parking lot.  And there is only a blue sky where a city skyline should be.  So what setting did I make to low and how should I fix it?

Edit: the problem is fixed, I just put it on well balanced and put some things on low, that I knew would not affect the edges.
